Ethanol vs Dimethyl Ether - Isomer Relationship
What is the relationship between Ethanol and Dimethyl Ether?
Same formula (C₂H₆O) but different functional groups. Ethanol is an alcohol (–OH); dimethyl ether is an ether (–O–).

Introduction
These molecules have the same atoms but are completely different compounds with different properties. How?
Formula Comparison
Both have the formula C₂H₆O — 2 carbons, 6 hydrogens, and 1 oxygen. Same formula means they could be isomers.
Connectivity Analysis
In ethanol, oxygen is at the end: C–C–O–H. In dimethyl ether, oxygen is in the middle: C–O–C. The bonding sequence is different.
Spatial Relationship
Different connectivity means these are constitutional isomers. No need to compare spatial arrangement.
Chirality Check
Neither molecule has a chiral center.
Classification
Constitutional isomers with different functional groups. Ethanol boils at 78°C; dimethyl ether boils at −24°C — dramatically different properties despite the same formula.
